xp32 to windows7 x64 problem !

hi everyone ,,

I'm having some troubles in upgrading from xp 2 windows 7

when i insert the CD and make to pc boot from it .. it doesnt
it tries to boot or something but then it logs in windows XP

when i click on the cd from my computer -> autorun

it says that its not a valid win32 application " maybe coz my pc is xp 32 bit "

also i downloaded the Windows 7 Upgrade Advisor and i passed the 64 bit test !

last but not least .. i have 2 harddisks inside my pc
one is the whole C [ 80GB ]
one is the D and the E [ 250GB ]

i'm willing to do a clean install ofcourse but would that only affect the windows harddisk [C] or it will affect all the harddisk inside my pc [the other hard disk has files too and i dont want to delete them , i need to buy another harddisk to back up]

thanks alot

A clean install is your only option ... an inplace upgrade is not available from xp to windows 7...

A litte add on to Tews post, you can not upgrade from any 32bit OS to any 64bit OS.

like i said b4

so how am i gonna do the clean install when it doesnt even work !

when i make the 1st booting from CD i get a line like

Boot from cd\dvd :> _

and it starts loading

after that it goes into windows xp and no installation window comes

it doesnt say anything like the normal [ press anykey to boot ]
